Frequently asked questions
How do I get exactly 1 inch per square?
Count the squares on your map (e.g., 30 across). Set the target width to 30 inches (76.2 cm). Each square prints at exactly 1 inch. Verify with the scale ruler.
Can I print on card stock?
Yes. GridPrint outputs a standard PDF — works with any media your printer supports, including card stock and photo paper.
What about maps from Dungeondraft or Inkarnate?
Export your map as PNG or JPG from any map-making tool. Upload to GridPrint, set the grid scale, print.
Can I skip pages I don't need?
Yes. Click any tile in the preview to exclude it. Useful for L-shaped dungeons where corner pages are empty.
